Italian Luca Parmitano nearly drowned when water from the suit's cooling system flooded into his helmet. Hopkins wore that same space suit on this exercise out, though it and Mastracchio's were fitted with several additional safety features, such as absorbent pads and snorkels. "

Snorkels?? For what? Breathing in the vacuum of space? Crashing into the ocean?

I guess they need to update the HGTTG to include: "Knowing where one's snorkel is"
